Guys, I'm starting on a 2003 CR 125 build. I will update with pictures periodically until I am finished. Hoping to have everything done in about a month.
The frame closest is the one I'm building. That's how I bought it... A basket of parts, and a chassis with some parts left on it.

Here's the bottom end of the motor and some misc. parts. The cases were powder coated cherry metallic red. I will be splitting the cases, stripping, and polishing them. As well as going through all bearings/ seals, and throwing new crank bearings in it.

6-speed transmission from a 1997 that will be going in. The cylinder/ head was just shipped to Eric Gorr to become a 134cc.

Much more to come. I'll keep everyone posted with updates.
As of now id like to thank Aktiv Motocross Graphics for the kit they are designing, and Advanced Coating Solutions in Fredericksburg for any Powdercoating work that will be done on the bike.

Got started on cleaning up the frame
Some of the new parts. Every bearing, bushing, hose, cable, etc will be replaced.
Some of the new plastics. New chain guide block and rub plate. It will have cycra stadium front #plate, and white rear fender. Going for the 2014 factory honda look.

How does everyone feel about Wiseco cranks? Should I just get OEM or hot rods?
Also, it will now be 134cc so is balancing the crank a necessity, a good idea, or no big deal? Any input will help.
The frame guard is full custom.
Anyone else think it looks broken? Looks like I'll have to get a whole right side case...
Anyone who knows a good route for me to take, that would be awesome. Wasn't expecting this.
Don't get me wrong, I want to build this bike RIGHT. When I look at the pictures where the shift fork, and everything is still in the cases though, it looks as though nothing even rides on this area. I would imagine that it broke when a bunch of stuff was floating around in the tranny (a clutch disc broke). Does anyone know if it is a crucial part to the case, or not? I found a side case on ebay, but I don't want to buy anything until I know if my case is salvageable.
Pit Row
If it was my bike, I would find another case half.
Tried one in my kid's '00 CR an it lasted less than an hour. I replaced the worn stock rod with an IMS I bought on ebay for $30 and it has been great (although I don't recommend rebuilding a Honda crank to anyone without access to a machine shop-it was a PAIN!).
I will be interested in this build. I think that with my kids all gone to college, I may send the head off to Gorr for the 134 treatment. I'll let you do all the testing for me first.
I ordered a right case earlier today, looking for a left one now. Good thing I'm turning this into a 6 speed, because these 5- speed gears are trashed!
I already had a cylinder and head that I sent out for bore, plating, porting, and head mod. I had planned on throwing a new crank, and the 6 speed tranny in it anyway. Now I'll end up with all new seals and bearings too... Basically a new motor.
With the money I'm putting in this bike I don't want to grab a used bottom end, with who knows how many hours on it. If I start from scratch, at least I know it's new.
I also went to the local Honda dealership, Fredericksburg Motorsports, and ordered EVERY bearing, seal, and gasket (all OEM) for the bottom end. I think it ended up being over 20 individual items.
As soon as my new cases come in I'll be able to get this thing going. Unfortunately I'll be in San Diego for the week during a work conference, so I won't get anything done.
I will be putting an hour meter on the bike and plan on tearing it down every 4-6 hrs for a ring anyway. I'm a 205lb B rider, so the bike is going to be struggling, that's for sure.
